Bruce Evans 258b53d151 Fix the variables $esp, $ds, $es, $fs, $gs and $ss in vm86 mode. ... Fix PC_REGS() so that printing of instructions works in some useful cases. ddb only understands a single flat address space, but this macro allows mapping $cs:$eip into vm86's flat address space well enough for the MI parts of ddb. This doesn't work for the MD parts that do stack traces, and there are no similar macros for data addresses. PC_REGS() has to use the trapframe pointer instead of the pcb for this. For other CPUs, the trapframe pointer is not available except by tracing back to it. But tracing back through vm86 trapframes is broken even starting with one.		2016-08-14 16:51:25 +00:00
